This invention relates to improvements in wire drawing machines. The object of the invention is to provide a wire drawing machine with a novel form of lubricating system and so controlled that lubricant is supplied the drawing mechanism only during the time that such drawing mechanism is in operation. I To this end the machine is provided with'a capstan, mechanism' for driving the capstan, aclutch for connecting thecapstan to and fromv the driv lubricating it, a valve being provided for 'ing-mechanism, a hollow die block arranged above the capstan, together with means for supplying lubricant to the interior of said die block forjlubricatingjthe dies in such quantity that it drains onto the capstan for controlling the-lubricant supply, tlie said valve and capstan clutch mechanism being so connected that the valve is opened and closed as the clutch is engaged and disengaged respectively.-

()ther objects'and advantages of the invention will be set forthin the following description and particularly pointed out in the appen'ded'claims. 1

The accompanying drawings illustrate one embodiment of the invention, 'inwhich:

Fig. 1 is a front elevation, parts being broken away, showing 'awire drawing machine embodying the features of the invention;

Fig. 2 is an enlarged fragmentary side elevation, partly in section, showing the mechanism for simultaneously stopping and starting the capstanand opening and closingthe valve for supplying lubricant to the die block;

Fig. 3 is an enlarged vertical sectional view 'of that portion of the capstan that is broken away 'in Fig. 2 and showing in detail the construction of the clutch mounted within the capstan,

Fig. 4 is. an enlarged detail view showing the connection between the rod for operating the capstan clutch and the levers for opening and 'closing the lubricant supply valve, and Fig. 5 is a'fragmentary sectional view taken on the lines 55 of Fig. 2 showing a front elevation ofsome of the valve parts.

Referring now to the drawings in detail in which like reference numerals designate similar parts throughout the several views,- 10 represents a framework which supports supported within" the a compartment 5 of substantially rectangular shape having top, bottom, back, and side walls 11, 12, 13, and 14 respectively. The

front of the compartment may be closed by v a suitable door or doors (not shown). The

Gil

wire drawing apparatus is mounted within this compartment and comprises a hor1zontally disposed shaft 18 upon which is mounted a plurality of integral capstans 17-1i of difierent diameters. The shaft 18 is driven through suitable gearing and a motor (not shown) carried by the framework 'and is coupled to and from-.the capstans through a clutch mechanism hereinafter described. Mounted abovethe shaft 18 are a plurality of sheaves l -independently rotatable u on a horizontally Qdisposed shaft 20 .suita ly compartment '5. Mounted between the sheaves 19 and cap- Stans 1717 is a die block 21 carried by a bracket 22 secured. to the backwall of the said compartment. For avdetailed' illustration and description 'of the sheaves 19. and the drii'ringmechanism for the capstan shaft 18 reference is made to applicants co-pending application, Serial No. 5 11,6313, filed March 7, 1922. The details of this construction havebeen omitted from the present application for the sake of simplicity, since a full description of the sheaves and driving mechanism for the capstan shaft 18 is not clutch disks 73 which are secured by a pin 74 to the inner peripheral wall of a cup-, shaped opening 5 made in: the capstans l717. The disks 72 and 73 are movable longitudinally on the pins 71 and 74 respec tively, and when pressure is exerted to force the disks together they form a driving connection between the capstans 17-17 and the sleeve'p18, as is readily understood. The

. essential to a complete understanding of the p The shaft 18 is in i The plate 76 is fastened to one end of a shaft means for forcing the disks 72 and 73 together comprises a plate 76 which engages the outermost disk, and when thesaid plate is moved toward the right, into the position shown serves to force the disks together sufficiently to cause them to rotate as a unlt.

77 mounted within the sleeve 18. A transverse pin 79 is secured in the shaft 77 and projects through diametrically opposite longitudinal slots 80 out in the sleeve 18 and engages an annular channel formed in the interior wall of a housing 78 so as to be movable longitudinally with but free to rotate independently of the said housing. Through the medium of the pin 79 and'slots 80, the shaft 77 and housing 78 are movable together longitudinally of the sleeve 18.

Means not shown) is provided for prevent-- ing' the housing from turning but permitting it to move longitudinally of the sleeve 18. Secured to the sides of the housing 78 at diametrically opposite points are pins 81 which receive the bifurcated ends of a forked member 82-which ispivoted at 83 to a link 84. The link 84: has secured to its free end a pin 85 which fits within a slot formed in the upper end of a vertically reciprocable rod 86.

For a more detailedillustration and description of the clutch mechanism per se ref erence is made .to the co-pending application of )V. F. Horsford, Serial No. 566,206, filed June 6, 1922.

When it is desired to revolve the capstans 17-17 the rod 86 is ,moved upwardly, as viewed in Fig. 2,;by means of a foot treadle,

, handle, or other suitable means (not shown).

a driving connection between'the sleeve 18 and capstans 17. When the means for raising the rod 86 is released, the said rod is restored to its initial position and the. housing 78 and shaft 77 moved toward the'left,

as viewed in Fig. 2, by means of "energystored in a compressed spring 87, which has one of its ends in engagement with the shaft- .77 and its other end against a plug 88 screwed within the end 'of the sleeve 18.

Thehousing 78 in moving toward the left,

as above described; engages a brake member 89 carried thereby against an annular member 90 secured to the capstan and serves to stop the rotation thereof;

Referring now to the lubricating system,

the die block 21 comprises a hollow, horizon I tally disposed body portion 22 .having secured thereto shelves 23 and 24, each of which is adapted to support a series of dies thereon (not shown). One end of the body portion 22 is provided with an opening 2 (Fig. 2) through whichprojeets a valve cas ing 28 provided with a series of openings 29 which communicate with the interior of the body portion 22. Suitably supported within the valve casing 28 is a valve 30 which is normally held on its seat by a compression spring 31. In communication with the valve 30 and suitably supported is a pipe 32 connected by an elbow 33 with a vertically disposed pipe 34 which is connected to the outlet port of apump 35. The intake port of the pump has connected thereto a. pipe 36- which is suitably supported within .an opening 37 formed in the bottom wall 12 of the compartment 5. Disposed above the bottom wall 12 and parallel therewith is a screen 38, the purpose of which will be hereinafter described.

When the capstans 17 are set in motion by raising the rod 86, as previously described,

the valve 30 is simultaneously opened by means of an arm 39 which is turned counterclockwise about' its pivot 91 to move the valve 40 off of its seat. The arm 39 is given the movement just described by means of a plunger 92 efciprocably mounted within a bearing 93 carried by the back wall 13 of the compartment 5,'one end of the said rod being in engagement with the arm 39 and its'other end having a pin and slot connection with a bell-crank lever 94 pivoted at 95 to a bracket 96 suitably supported by the framework of the machine. Pivoted to the bell-crank lever 94 is one end of a link 96, the lower end of'whieh is pivoted at97 to an arm 98 pivotally mounted upon a stud 99 carried by the framework of the machine. The arm 98 is provided with a projection 1.00 which fits within 'a recess 101 formed in the rod 86 (Fig. 4:). s i

The pump 35 serves to draw lubricant placed in the compartment 5 and lift it into the interior of the body portion 22 of the die block, from whichiit is forced on top of.

the dies supported on the shelves 23 and 2 1 through aseries of openings 23' and 24 respectively. Fora detailed description and disclosure of the construction, ofthe die block reference is made to the co-pending application ofF. S. Kochendorfer, Serial No. 566,285, filed June 6, 1922. The lubricant is supplied to the dies in such quantities thatit' overflows the shelves 23 and 2 1 and drops onto the capstans 17 mounted be neath' the die block and serves to thoroughly lubricate said capstans. Excess lubricant supplied to the 'capstans drains therefrom through the screen 38 onto the bottom'12 of the compartment, from which it is again lifted into the interior of the die block by the'pump 35. V K I Due to the construction of the lubricating system just described and the operativeconnection between the clutch for stopping and starting the capstan andthe valve for. controlling the supply oflubricant to the d1e block, the, wire drawing apparatus is only lubricated during such times as i't is in operation, and whenever the capstan is stopped,

the lubricant is cut off; Since the flowof lubricant is controlled automatically by the stopping and starting of the capstan, whenever the capstan is in operation sufficient lubricant is insured, the supply of which is not dependent upon the discretion of the operator, and when the capstan is idle no lubri cant is supplied the dies o'rcapstan, which opened and closed asthe capstan is connected to and disconnected from the drivin means respectively. v
